Model 3CAV Triple Conditioned Air Vestibule

 

ADS-402

The Model 3CAV is primarily used between rooms with extreme temperature differences and very high traffic.

The frost elimination cycle is similar to the Model DCAV but the additional vestibule improves efficiency as well as increases the model's temperature range applicability. 

The Model 3CAV automatically adjusts as conditions change to optimize performance and reduce energy consumption.

With the use of HCR sensors and software, Model 3CAV can be integrated into a facility's refrigeration control and monitoring system.  This allows both remote monitoring and remote adjusting of the HCR equipment.
